Problems solved by technology

[0003] At present, drought-resistant ingredients are also applied in fertilizer addition technology in production. It is more common to use high-molecular polymers with strong water absorption as water-retaining agents to add to fertilizers for soaking crops or dressing orders to improve drought-resistant effects. It can work at the seedling stage of crops; there are also anti-transpiration agents, which are sprayed on the leaves of crops after adding foliar fertilizers, so that the agents can act on the stomata to reduce water loss, but the drought resistance is not stable, and it will also damage the leaves. Effects on photosynthesis
In recent years, although drought-resistant additives that can be used for both seedling treatment and adult plant spraying have appeared on the market, most of these additives are compounded of various chemical components, and the components are complex. The safety of crops needs to be discussed, and the application cost is high
Therefore the drought-resistant effect of existing anti-drought additive is very limited, and action is single, can't improve the nutritional status of plant

Embodiment 1

[0026] S10, according to 40% of fulvic acid, 20% of trace element chelates (trace elements include Fe, Cu, Zn, Mn, B added in equal proportions, used for trace element chelate ligands), proline 20 %, 20% of the seaweed extract, after mixing, it becomes the fertilizer synergist for improving drought resistance in Example 1; wherein, the above raw materials are all purchased directly from the market.

[0027] S20, in order to verify the effect, the above-mentioned synergist is mixed with a large amount of elemental fertilizer components, and after the drought-resistant fertilizer of the present invention is made, it is used for a planting test: a pot test is used to plant Shanghai Qingming, and a total of 6 treatments are established, and each treatment is performed 5 times Repeat, a total of 30 pots, 3 plants are sown in each pot, and 1 plant is planted. Simulate the dry soil during planting to control the soil humidity of pot picking. After planting, the wilting degree, wiltin...

Embodiment 2

[0029] S10, according to fulvic acid 45%, trace element chelate 15% (comprising Fe, Cu, Zn, Mn, B, Mo, Ni added in equal proportions in the trace element, the chelating ligand of trace element adopts dimethyl Sodium dithiocarbamate, oxalic acid, histidine, malic acid these several), proline 20%, the ratio of seaweed extract 20%, after mixing, it is the fertilizer synergism for improving the drought resistance ability of the present embodiment 2 agent; wherein, the above raw materials are directly purchased from the market to obtain

[0030] S20, further in order to verify the effect, in the same manner as in Example 1, the above-mentioned synergist was mixed with the macronutrient fertilizer components to prepare the drought-resistant fertilizer of the present invention, and then used for planting tests: using pot experiments to plant Shanghai Qingming, a total of Set up 6 treatments, each treatment was repeated 5 times, a total of 30 pots, 3 plants were sown in each pot, and ...

Embodiment 3

[0032] S10, select 1Kg of high-quality kelp, agaricus, Gracilaria, and seaweed, add 7L of water to soak for 3 hours, stir and wash, drain; and wash again in this way for 4 times until clean, dry and finely grind to 2-5mm, Transfer to digestion vessel;

[0033] S20, add 100mL 5wt% sodium bicarbonate solution to the digestion container and soak for 30-50min, then add the mixed enzyme solution of cellulase, xylanase, pectinase and papain, stir for 3h and then stop , the enzymolysis slurry is usually heated to inactivate the compound enzyme; then, the slurry is centrifuged, the insoluble precipitate is discarded, the supernatant is taken as the enzymolysis solution, and then spray-dried is the seaweed extract prepared in this example ;

[0034] S30, according to 50% of fulvic acid, 10% of trace element chelate (trace elements include Fe, Zn, B, Mo, Ni added in equal proportions, EDTA, dimethyl di Sodium thioformate, histidine (these several), proline 20%, seaweed extract 20% rat...

Abstract

The invention discloses a fertilizer synergist capable of improving the drought resistance ability. The fertilizer synergist comprises 45%-60% of fulvic acid, 10%-25% of microelement chelate, 10%-20%of proline, and 15%-25% of alga extract. The invention further provides a drought resistant fertilizer comprising the fertilizer synergist capable of improving the drought resistance capability. Due to an exogenetic biological stimulant and various active ingredients, the fertilizer synergist capable of improving the drought resistance capability aims at improving the soil activity, strengtheningthe activities of microorganisms and enzymes in the soil, promoting the growth of a plant root system, and externally improving the drought resistance capability of the plant, and aims at stimulatingthe activation of water resistant stress factors in the crop, so that the drought resistance ability of the crop is improved through cooperation.

Description

technical field [0001] The invention relates to the technical field of fertilizer additives, in particular to a fertilizer synergist and a drought-resistant fertilizer for improving drought resistance. Background technique [0002] The total amount of water resources in my country ranks sixth in the world, but the per capita water possession is only 2,400 cubic meters, which is 1 / 4 of the world's per capita share. my country is facing a more serious water shortage problem. Agricultural water accounts for about 70% of the total water consumption. Drought seriously restricts the increase of crop production in our country. Studies have shown that under drought conditions, osmotic adjustment substances in plants such as soluble sugars, inorganic ions, free amino acids, etc., certain protective enzymes, endogenous hormones and other substances will increase to varying degrees, directly or indirectly regulating plant growth. function to enhance the drought resistance of wheat. T...
